[Prior art]

 By the way, "kick board" is an extremely light, low-cost, and extremely recreational exercise equipment.Therefore, there is a tendency to use kick boards as leisure, health-holding or foot-changing equipment. ing. Therefore, in addition to the need for good vehicle safety, comfort and convenience when riding are also increasingly valued.

FIGS. 5 and 6 show a conventional kick board, in which a head bracket 2 is provided on a front end side of a tread plate 1, and both sides of the head bracket 2 have respective bearing seats 3. One end 301 is pivotally supported, and a control stick 4 is integrally fixed on the upper end surface of the head bracket 2 in an upright manner. A regulating plate 201 is vertically protruded substantially at the center of the bottom surface of the head bracket 2. At the same time, the interlocking rod 5 is loosely inserted into the restricting plate 201, and springs 501 are respectively provided around the abdomen of the interlocking rod 5 on both sides of the restricting plate 201, and both ends of the interlocking rod 5 are connected to the other end 303 of each bearing seat 3, respectively. To pivotally support the front wheels 6 in orthogonal directions to bearings 302 projecting from the center of the bearing seat 3. Therefore, both ends of the head bracket 2 and the interlocking rod 5 and both ends 301 and 303 of each bearing seat 3 form a parallelogram link mechanism, and the load applied to the tread plate 1 is appropriately changed to the left or right depending on the direction to be changed. When the vehicle is deflected to the right, the front wheel 6 on one side is deflected by the load, and the bearing seat 3 can be pulled to change the direction. At the same time, the interlocking rod 5 is pushed, and the interlocking rod 5 is regulated. By projecting to the other end of the plate 201 and pushing the bearing seat 3 at the other end, the other front wheel 6 is interlocked and displaced, and the entire kick board can be turned. Then, if the load applied to the tread plate 1 is returned to the center and the equilibrium state is maintained, the interlocking rod 5 returns to the original position by the elastic return force of the spring 501, and the front wheel 6 moves the normal direction. It can be linked and returned when it is needed. However, it can be said that the structure for changing the direction of the front wheel 6 by biasing the load applied to the tread plate 1 can achieve the purpose of changing the direction. There is.

Since the control stick 4 is directly attached directly to the upper end surface of the head bracket 2 and has no direct relation to the steering operation of the front wheel 6, a certain technique such as skiing or skating is required. And it is difficult for beginners to control. Steering of the front wheel 6 involves the lateral displacement of the interlocking rod 5, but in a situation where the interlocking rod 5 is simply regulated by the restricting plate 201, the stability is clearly higher. In addition, when the interlocking rod 5 is displaced, there is a frictional resistance between the interlocking rod 5 and the regulating plate 201. An elephant is generated, which makes steering difficult and causes danger.
